In 1940, Mueller played for the Beaumont Exporters in the Texas League and threw a no-hitter on August 22, 1940 against Dallas. The following year, Mueller reached the big leagues, pitching four games for the Detroit Tigers. He enlisted in the Army after the United States entered World War II and missed the next three seasons. After a physical revealed that he had a hernia, Mueller received a medical discharge in late 1944.
Mueller rejoined the Tigers for the 1945 season, going 6-8 in 26 games, including 18 games as a starter.
On April 17, 1945, Mueller faced Pete Gray, the St. Louis Browns' famous one-armed outfielder, in Gray's first major league game. Gray got his first major league hit off Mueller, the first of 51 hits for Gray in 1945.
On July 21, 1945, Mueller put in one of the greatest pitching performances in major league history. Mueller pitched the first 19-2/3 innings for the Tigers and left having given up only one unearned run. No pitcher has thrown as many innings in a major league game since Mueller's feat. The game lasted 4 hours and 48 minutes before umpire Bill Summers called the game a tie due to darkness at 7:48 p.m.
Mueller also pitched two scoreless innings in Game 1 of the 1945 World Series.
After his baseball career ended, Mueller returned to Belleville, Illinois, where he worked in the family's furniture store until he retired in 1974.
